FLANGIN G--MA CHINE Specification of Letters Patent.

Patented March 2, 1909.

Application led September 13, 1907, Serial No. 392,627.

To all whom it may concern:

Be it known that l, CLARENCE L. Einen, oi the city of Rochester', countyof Monroe, and State of New York, have invented. certain new and usefulImprovements in Flanging- Machines; and l do hereby declare theiollowing to be a full, clear, and exact descri ition of the same,reference being had to t ie accompanying drawings, forming a part of thespecification, and to the reference-nu merals marked thereon.

The present invention, which relates to machines for Hanging metallicbands, pipes, tank sections or other open ended hollow bo'dics, has foran object to provide a construction which will cost less to manufactureand will reduce the time required for i'langing the two ends of a hollowbody, thus providing an increased output for the machine.

Another object is to provide a construcf tion by which the hand trimmingof the ilanges is obviated.

To these and other ends the inventionconsists in certain improvementsand combinations of parts all as will be hereinafter more fullydescribed, the novel features being pointed out in the claims at the endof the specification.

ln the drawings: Figure 1 represents a front elevation of a machineconstructed in accordance with my invention. Fig. 2 represents a sideIelevation with one of the bend ing devices shown in vertical section.Fig. 3 shows a horizontal section ol the chuck or holder, the cutting,bending and supporting devices being shown in plan before thc llange isformed. Fig. 4 is a detail view showing the position of the parts afterbending. Fig. 5 is a detail View showing the operative position ofanother l'orxn of cutting device, and Fig. 6 shows ,the machine arrangedto cut smaller bands. f

ln the production of llanges on bands of large diameter such as thoseused in the construction of beer vats it is customary to hohl or supportthe section -or band in such a manner that not only are very heavy andconscquently expensive parts required but it is impossible to produceover one llange at cachI operation, and, as thcse operations are veryslow, the cost of making a section flanged at both ends is very great.By a machine constructed in accordance with this invention the ring issupported interiorly, thus making it possible to reduce the weight andconsequently the cost of the machine, and at 'the same time to forni a(lange at both ends simultaneously.

In the embodiment ol the invention herein shown there is employed a bedplate lon which preferably is arranged supports 2 on the upper portionsof which journaled a shaft or spindle 3 which carries the chuck orrotary holder'.1 The chuck is llormed preferably by arranging at one endof the shaft 3 a head 4, the outer face oi which preferably has aplurality of jaws 5 movable thereon, being for this purpose formed withradial guides on which move slides 7 to which the jaws 5 are secured bybolts 8, permitting their removal and the attachment of other jaws 5L ofdifferent length. All oi'v the jaws have their outer laces curved Anearboth edges at 5X so that when the chuck is expanded they will lic iiushagainst the inner surface of the band. The expansion oi the jaws isefected by any suitablemeans, but it is preferred to connect them bylinks 9 to a plunger i0, the links being united to the plunger by twodisks il and 12 arranged bctween a flange 13 and a nut 14 on the plungerand receiving pivots 15 integral with the links. The plunger is mountedin the shaft 3 which for this purpose is made hollow, while to the outerend of the shaft is secured a` iluid pressure cylinder l() which rotateswith the shaft and has its piston 17 connected to the plunger l0. j

ln order to rotate the chuck or holder, it is preferred to employ aninternal gear 18 integral with thc inner face oi the hcad 4 and having adrive shai t IQ-geared thereto by a' I iin ion 20, said shaft 1l) beingalso journaled on the supports 2. t 'i Arranged to operate on theprojecting edges of a band positioned on the chuck Yare thebendingdevices which. in this instance are in the form o'l rollers 2leach mounted so iis-to swing about an axis coincident with a portion oi'a peripheral edge of the chuck, and

adjustable in a direction parallel. to the turning axis of the chuck andalso in a direction transverse to said axis. For this purpose .l ,mayprovide the bed 1 with grooves or guides Q2 in which work bolts .23carried by supports 24-011 cach oi which a carrier 25 is guided to bedriven by a motor shaft Qt-jouinaled in the support or by a manuallyoperable shaft 27 journaled inthe carrier, this double ad justine nt oithe carrier being accomplished by v`Ir/lo carrier 29 the adjustment ofwhich is effected' ende,

awormwheel 28 with which a worm' on shaft 27 meshes, and which has ascrew threadedv connection with shaft 26 so that the rotation et eithershalt will'eiiect theadjustment of the carrier. Movable on a carrier 25in a direction parallel to the axis of the chuck is a by a motor shaft3() and a manually operable shaft 3l by means of a worin wheel 32mounted in a'manner similar to the -worm 28. This carrier 29 is providedon one oi its sides with a semicircular or arcuate guide 33 on whichtravels the bender carrier 34, the adjustment of the latter beingeiected by a worm shaft i 35 meshing with a curved rack 36, on the car-'.lhe bender dev1ce 21 1s journaled y ri'er 3e. on said carrier 34 so asto engage a rejecting portion of a band on the chuck. n order to supportthose portions of the band in proximity to the bending devices, l employsup porting devices preferably in the form of rollers 39 in thisinstance, secured to opposite ends oi a shaft ,'ournaled on a carrier 40which is adjustable on a sup ort 4.1 toward and from the chuck ai'tereaclii operation by means et screw shaft 42, or other means, the supportel being also adjustable on bed plate l in order to obtain a coarse orrough adjustment by bolts 43 or other means.

Mounted on that side of the chuck opposite the bending devices so as tooperate ma direction parallel to the axis" oi the chuck, are the cuttingdevices, one for the flange at each end of a band. These cutting devicesin the lpreiierred iform are mounted on a support 44 roughly adjustableto and from the chuck on the bed plate for ditl'erent sizes of bands bybolts 45, for other means, and having a carrier 46 adjustable also toand from the chuck citer each bending operation by a screw shaft 47. @nthis carrier is arranged the cutting device which may consist of twoarms 48 pivoted together at 49 vand at their free ends carrying rollercutters 50 which are forced together gradually to cut from oppositesides of atlange by means of a yoke or link 51 having a set screw 52.Another embodiment of the cutting device is shown in Fig. 5, wherein oneci the arms 48a is longer than the other, while the roller cutter 508L1s a flat roller and 'the cutter 50b has a knife edge and is mounted onthe shorter arm and bears on the flange at one edge of the roller 50.

ln o eration, the chuck is provided with jaws w ich wher in clampingposition vwill exactly tit the inner wall of the band to be flanged. Uon the surrounding of the chuck by the ban the jaws are moved outwardlyby means of fluid admitted undef' pressure into the cylinder through ailexibh piping 38, or ether device, which permits the rotation of thecylinder. At the end of the movement of the is positie- :u

and 11s a :onsequence inward than their outer alockmg of the the linkshave their inner ends` i y I'v 914,034

jaws takes place, the fluid in the cylinder preventing their unlockingdue to jars orother causes. As a further means for holding the jawsagainst movement, the proximate edges of the jaws are interlocked as byclamping plates 40 sedured to head 4 by bolts 41. The rollers 21 arenowadjusted so that their eripheries are in a lane with a portion of t eperiphery of the c uck and engage the inner face of the band, as shownin Fig. 3, and the su porting devices are 'adjusted to bear on tli edgeslocated at the points where the flanges proceedfrom the band. Upon therotation of the chuck the rollers 21 are'turned gradually oy-'means ofthe shaft 35 and the sup.- porting devices 39 bear upon the band 1nproximity thereto to prevent undesirable ending. After the band is comleted or4 during the last portion of the ben ing opern ation, thecuttingdevices are engagedwith the flange and flanges of equal width arethus, secured. i

Of course, when the jaws 5%* are of less length than the head 4 as inFig. 6, it is ossible to form flanges at only one end of a and. In both.embodiments during the removal and the fitting of a 'band it isunnecessary to move the supports of the several devices on the bed platel, as these devices may be moved away from the chuck .by moving thecarriers on the su ports.

From the foregoing it will be noted that I have provided a machine bywhich the manufacture of flanged open ended lhollow bodies may beaccomplished in a very short time and that the flanges produced thereb"are trimmed to a uniform width.
